U.S. Stock losses grew heavier on Wednesday as the afternoon wore-on with a selloff in crude oil and health care stocks leading Wall Street into the red. Crude settled at a one-week low after a weekly reading on U.S. oil inventories showed a build. Health care stocks sold off in late-afternoon trading after harsh comments from presidential candidate Hillary Clinton over Mylan's (MYL - Get Report) pricing of its EpiPen. The drug company has quintupled the price of the life-saving allergy medication since 2007. Intuit (INTU - Get Report) slid after issuing conservative earnings and sales guidance for its fiscal first quarter and full year. The TurboTax developer also announced a $0.34 a share dividend, up from $0.30 a sahre. Ford (F - Get Report) declined after recalling more than 88,000 vehicles due to an engine-stalling defect. The automaker knows of no accidents or injuries tied to the issue.
